TIBE-PATGHING APPLIANCE.

Application filed January 24, 1927. Serial No. 163,266.

My invention relates to a tire patching appliance of a type suitable for use in connection with tubes of cementing compound used to apply rubber patches to the inner tubes of automobiles or other rubber articles.

In making a cold patch, as patches of the above type are generally termed in the trade, it is necessary that the rubber surface to be patched shall receive preliminary treatment that will insure the patch holding and ance itself, so that both are always at hand for the patching operation.

With these several ob 'ects in view I have designed a tube holder of metal which provides of itself not only protection for'the tube but also an abrading surface suitably positioned for convenient use, a scraping surface also most convenientfor use, and in addition thereto a roller which, as a matter of convenience and economical construction, is mounted on a rivet or pin which secures the front flanges of the tube holder. appliance in position embracing the forward end of the tube.

It is a distinctive feature of my invention that the scraping surface conforms substan= t-ially with the taper at the end of a full tube of cement and that this scraping surface should terminate in a wide'scraping edge which projects above the top level of the mounted tube.

It is a further distinctive advantage that the body portion of the tube should be held down and also protected by bendable flanges which do not interfere with the access to the tube to express all of the cement there from.

It is a further distinctive advantage that the tube shall be held in position under the bendable and the roller holding fiangeabeing prevented by movement in one direction by the inclined abrading surface and in the other direction by an upturned lip engaging Y curved portions forming a continuationiot the curved bot-tom of the body 5 and the thefront end of the tube so as to hold it in position with its end cap exposed for convenient removal and replacement.

My invention further comprises the various novel details of construction and arrangements of parts, which are obviously susceptible of wide variation but which intheir preferred embodiment only are illustrated in the accompanying drawings which form. apart of this specification, and in Which:'

Fig. 1 is a pliance.

Fig. 2 is a side view; and Fig 3 is a bottom view .of Fig. 1. Fig. 4 is a front end view of Fig. 2. Similar reference numerals lar parts throughout. 7.

In the embodiment of my invention illustrated, I show the appliance as comprising a semi-tubular body portion 5, preferably formed by a, metal stamping, WhichcOrrespends substantially to the shape of the tube 6 of cement which is intended to be received therein. This tube corresponds to the usual plan View of my improved aptype of cement tube now'on the market and is provided at its forward end with a threaded nipple 7 closed by a screw capv 8. At its other end 9 the sides of-the tube converge and are joined together.

curved portions 10 and upright ends 11 the ends 11 forming vertical spaced parallel. Walls which receive a rivet or pin 12 on which atlat faced roller 13 is mounted free to rotate. This roller is preferably mounted near the, upper front corners of the ends 11 so that its periphery is exposed both above and to the front of the appliance. .A lip 14 at the bottom of thefront end of the body 5 is bent up so asto engage the slightly tapered front end 15 Of the tube 6 and hold the tube from slipping out forwardly through the appliance and yet leaving its cap 8: exposed and its nipple end clear the appliance so that the cement, as expressed therefrom, can be applied to the sur face to be treated.

Substantially midway of thebody portion 1: provide apair of bendable flanges 15 relate to simi- The :main. body portion hot the appliance is prov ded at its forward end with two flanges comprisingv which are formed in upright position and after the tube is in place are bent down over it, as shown in Fig. 1, thus holding it in the appliance while leaving the major portion of the tubes body exposed so that by pressing upon it the contents of the tube can be forced out.

Inasmuch as the tube 6 tends to widen as it approaches its flat end, so the body 5 of the appliance flares in substantial accordance with the tube and is thus provided with divergent side edges 17. In like man ner the body portion 18' at the rear end of the tubular body is sloped up at an angle of approximately 4-59a'nd conforms substantially to the angle of the base of the tube and this surface is provided withroug'hened serrations or vspuds 19 which are distributedoverit so as to provide an effective scraping means for removlng grease, dlrt and foreign matter from the surface to be patched. At

' the rear end of this inclined portion 18, I

provide a further planeextension '20 which is inclined slightly rearwardly from vertical plane and which projects above the level of the tube in theappl ance. The

. walls 17 forming the side of the rear end of the appliance have their upper edges rising at an incline towards and joining the side edges of the scraper extension 20 but they leave about half of the scraper blade standing clear above them. In other words, these sides extend approximately to the top level of the tube and this with the flanges 10 and thedrawings, my device is employed in the following Imann'e'r in connection with the making of a patch. FlISlZ the instrument 1s grasped in the hand with the index and middle fingers pressing against the surface 20 and in this position the abradlng surface 18' is conveniently'held tobe worked over a horizontal surface. I be'patched is then thoroughly scraped and abraded by the surface 18 and when it has- The rubber surface to been cleaned in this manner the appliance is reversed in the hand, the cap 8 is removed and with the thumb pressing upon the rear end of the tube-the cement is forced out and applied to the treated surface. The cap istlien'applied to the'tube, the holder is reversed and inverted and with the fore finger bearing on the back of the scraper 20 the cement is spread over the surface and then the surplus cement is scraped away. The patch is then applied to the cemented surface, the holder is again reversed and inverted and with the fore finger pressing on the bottom of the holder adjacent to the lug 14, the roller 18 is in convenient position to be pressed upon and rolled back and forth over the patch so as to insure complete adconstrued that I am limited. thereto, as

changes in arrangement and substitution of equivalents may be made by those skilled in the art without departing from the-invention as defined in the appended claims.

Having thus described my invention, what I claimas new and desire to secure by Letters Patent, is

1. An appliance of the character de scribed, comprising a trough-like body shaped to receive a tube of cement, said body having side and end flangesfadapted to hold such a tube inposition therein with its cap end projecting andits body sufiicie'ntl-y exposed to permit its contents to be pressed out. V

2. An applianceas describedinclaiml,

which the side flanges are freely bendable to permit of the insertion of the tube in the body.

3. An appliance as described in claim 1,

in which the end flanges comprise a lip at the top'end of the tube and a sloping roughened surface at the Ebottom end of the tube.

4. An appliance of 1 the character described, comprising abody shaped to -re-' celve and partly enclose a tube of cement,

.6. An appliance according to claim 5, in

whichsaid flanges are pivotally connected bya bearing pin for the roller that is interposedbetween them.

In testimony whereof I affix my signature.
